Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Cabot
- Not actively maintained; the maintainers are seeking new owners and releases stopped years ago
- Older Django/Python stack with dated dependencies
- No public status page feature
- No multi-region probing; limited to single-instance checks
Prometheus
- No built-in dashboards UI; you must pair it with Grafana
- Long-term storage and horizontal scale need add-ons (Thanos, Cortex, Mimir)
- No logs, traces, or APM out of the box (metrics only)
- Steeper operational learning curve than turnkey Datadog
Bottom line
Both are a similar lift to self-host; choose Prometheus for the larger community and ecosystem. Prometheus has seen more recent development. Open each guide below for deploy steps and the full feature gap.
